  "abstract": "BackgroundCyphenothrin is a widely used type II pyrethroid insecticide. Its regulatory risk assessment, like that of most pesticides, is based primarily on the active ingredient, leaving the genotoxic potential of encapsulated commercial formulations such as Bombex Farumy largely uncharacterized.MethodsWe compared cytotoxic (propidium iodide exclusion) and genotoxic (alkaline comet assay) effects of cyphenothrin active ingredient versus its microencapsulated and released formulations in human HL60 and HepG2 cells following 1 h exposures.ResultsRelative to the active ingredient, DNA damage indicators were numerically lower for encapsulated Bombex Farumy by 29%–83% (median 61%) at concentrations where the active ingredient differed significantly from control. Encapsulated Bombex Farumy showed minimal effects overall, although significant, nonmonotonic increases in tail length and tail moment occurred at select concentrations in HL60, and modest elevations were observed in HepG2 only at 1,000 µM. Released Bombex Farumy showed numerically intermediate effects, but direct pairwise contrasts between released and encapsulated Bombex Farumy were not statistically significant at any concentration or endpoint after correction for multiple comparisons.ConclusionIn this exploratory, hypothesis generating study, DNA damage indicators were numerically lower for encapsulated than for released formulation or active ingredient cyphenothrin, but direct statistical contrasts between formulations did not reach significance, so a mitigating effect of microencapsulation remains uncertain. Nevertheless, even these preliminary findings suggest that regulatory frameworks relying only on active ingredients may not fully capture formulation specific risks, supporting the need for confirmatory, adequately powered, regulatory compliant testing.",
